Our world is full of light, and we depend upon it to power life on our planet. So it is appropriate to honor three scientists who invented new ways of using light rays to explore our world. The 2018 Nobel Prize in physic...

First suicide attempts are more lethal than previously realized, reports a study of children and adolescents.

Researchers have discovered a common process in the development of late-stage, small cell cancers of the prostate and lung. These shared molecular mechanisms could lead to the development of drugs to treat not just prost...

A team of scientists has successfully trained a new artificial intelligence (AI) algorithm to make accurate predictions regarding cognitive decline leading to Alzheimer's disease.

Malaria-infected red blood cells trigger the immune system's first line of defense by releasing small vesicles that activate a pathogen recognition receptor called MDA5, according to a new study.

After unearthing and analyzing handwritten documentation from scientist Samuel Morton, a doctoral candidate drew a new conclusion about the infamous 19th-century collection: though Morton accurately measured the brain si...

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, miscarriages, birth defec...

For children born with Saul-Wilson syndrome, and their parents, much of their lives are spent searching for answers. First defined in 1990, only 14 cases are known worldwide. Today, these individuals have answers. A stud...

Venomous snakebites affect 2.5 million people, and annually cause more than 100,000 deaths and leave 400,000 individuals with permanent physical and psychological trauma each year. Researchers have now described a new ap...

Non-invasive prenatal testing potentially provides a wealth of genetic information, but the quality of the DNA sequencing is poor -- only about 10 percent coverage per genome. Nevertheless, scientists now show that with ...

A discovery may open up new ways to control steroid hormone-mediated processes, including growth and development in insects, and sexual maturation, immunity, and cancer progression in humans.

A new DNA tool can accurately predict people's height, and more importantly, could potentially assess their risk for serious illnesses, such as heart disease and cancer.

Scientists have discovered the role of an immune system double agent. This molecule, called USP18, can help curtail immune responses, but it can also open the door to bacterial infections, such as harmful listeria and st...

A new study found that women who reported taking a low-dose aspirin every day had a 23 percent lower risk of ovarian cancer compared to nonaspirin users. The research also found that women who were heavy users of nonaspi...

In research that extends knowledge about the physiology of regeneration and wound repair, biologists have discovered that amputation of one limb is immediately reflected in the bioelectric properties of the contralateral...

Chemotherapy drugs to treat breast cancer may promote muscle mitochondrial dysfunction, according to new research. Dysfunctional mitochondria, the energy centers of the cells, may contribute to fatigue and weakness that ...

While liver biopsies are powerful and reliable, they are also invasive, painful, limited and subject to complications. These effects may soon be a thing of the past for some patients thanks to new research showing PET im...

A specialized measuring machine at SLAC is helping scientists build precise detectors for the ATLAS experiment. When physicist Katy Grimm and her students began using SLAC National Accelerator Laboratory's coordinate mea...

Researchers shed light on how people decide whether certain behaviors are moral or immoral.

Researchers have created a new deep learning system that can determine if a news outlet is accurate or biased based on only 150 articles published. The algorithm can also detect the political leanings of a news site. Res...
